We finish up with a quick word about the future study of \((D+1)\) -colored graphs. Clearly, we have just scratched the surface here. The combinatorial, topological, algebraic and metric properties deserve a much more extensive analysis. This could have many benefits: by analyzing a broader set of graphs, one would hopefully escape the branched polymer phase in the continuum limit. (In fact, such work has begun [1]}, [2]}, but branched polymers have so far proved resilient.)
